Privacy policy and Terms

This is the privacy statement of Focus JJ Amsterdam (registered in the Trade Register of the Chamber of Commerce as Flow State Martial Arts B.V. under number 82279942).

Membership forms:


We offer memberships that are paid monthly or yearly, in the 2 times per week or unlimited variations.

  1. Membership fees of monthly subscriptions are due before the first of each month. You may pay by direct debit, credit card or by bank transfering your membership fees. Monthly membership types are automatically renewed each month. We have a 30 day cancellation policy.

  2. Membership fees of yearly subscriptions have to be paid in advance and in full at the start of your yearly membership. This membership will automatically end after said year. Afterwards you may purchase a new yearly membership. Should you want to quit before the end of the year you've purchased, we offer no refunds.

  3. The 2 times per week subscription gives you 8 credits each month, which expire at the end of each month. If a technique class is followed by an open mat or live sparring, this counts as one class. For these classes, you only need to register for one of the two classes in the app. 

  4. The unlimited classes subscription gives you access to all regular classes (including open mats, live sparring, etc). The sole exception being kids classes if you are an adult and vice-versa.

By training at Focus JJ Amsterdam, you agree with and will adhere to the Focus JJ Amsterdam


Code of Conduct:


  1. Be respectful towards your training partners. 

  2. Act responsibly: train seriously and be mindful of your partner's weight and skill level.

  3. Always respect the tap.

  4. Most injuries happen because of unnecessary accidents, so mind the people around you when you train and/or spar.

  5. Maintain good hygiene: trim your nails, wear a clean gi and wash your gi after each class. Wear flip flops or cover your feet when walking off the mat.

  6. Enjoy your time on the mat!




I realize practicing any form of martial arts bears an inherent risk and may lead to injury. To the best of my knowledge, I am in good physical condition and fully able to participate in each class. I voluntarily assume full responsibility for any risks or loss, property damage or personal injury, including death, that may be sustained by me, or loss or damage to property owned by me, as a result of participation in each class or open mat.

By training at Focus JJ Amsterdam, I acknowledge that I have read the foregoing waiver of liability and I agree not to hold Focus JJ Amsterdam or any of its employees/trainers accountable for any risk or loss of property damage, injuries or death I might sustain whilst participating in each class or open mat.
